Model Free Data-Driven Scheme to Assess Transient Instability of Solar Energy Penetrated Power System

The solar energy penetration reduces the time required for grids to adapt the frequency variations and re-equipoise the generation-demand equivalency. The performance and stability of the power system are thus challenged by such interconnections. This article suggests a novel synchronized data-driven method to assess grid stability of solar energy integrated power systems. To assess impending system transient instability, novel Early Instability Assessment (EIA) is proposed. The proposed method conforms to the real-time data, enabling the proposal an effective method to identify the upcoming unstable settings. The simulation results testify the applicability of the proposal on the system performance under various topological modifications, both in the presence and absence of solar energy penetration.
